|
||||||
|
.PP
|
||||||
|
It also supports a daemon mode (using --daemon) where the chroot session is run under

.TP
|
||||||
|
.B connect
|
||||||
|

||||||
|
.TP
|
||||||
|
.B disconnect
|
||||||
|

# chroot_manager.sh

|

|
# A fully featured chroot management tool with:
|
||||||
|
# - A command-line interface (create, connect, disconnect, status, help, install, uninstall)
|
||||||
|
# - Improved error handling and logging
|
||||||
|
# - A verbose/debug mode (--verbose)
|
||||||
|
# - A daemon mode (--daemon) which, when used with connect, will run
|
||||||
|
# the chroot session under strace to log all activity (system calls) in separate files.
|
||||||
|
#
|
||||||
|
# Requirements:
|
||||||
|
# - Some commands (create, connect, disconnect, install, uninstall) must be run as root.

#
|
||||||
|
# Note:
|
||||||
|
# By default, the script assumes the chroot jail is located at /var/chroot.
|
||||||
|
# When using --daemon, the log files will be stored in a directory created in the
|
||||||
|
# current working directory (default: "chroot_daemon_logs"). After the chroot session ends,
|
||||||
|
# the script will attempt to rename each log file based on the traced program’s name (if available)
|

|
# and ignore logs for trivial commands. Finally, the script will adjust ownership and permissions
|

# on that directory and its contents so they are accessible to the invoking user.

chroot_manager.sh - A chroot management tool
|
||||||
|
|
||||||
|
Usage:
|
||||||
|
sudo $0 [--verbose] [--daemon] <command>
|
||||||
|
|
||||||
|
Commands:
|
||||||
|
create
|
||||||
|
Create the chroot jail using debootstrap.
|
||||||
|
Sets up a minimal Debian environment in \$CHROOT_DIR.
|
||||||
|
|
||||||
|
connect
|
||||||
|
Mount necessary filesystems (dev, proc, sys, tmp) into the chroot,
|
||||||
|
set up X access, and then enter the chroot environment.
|
||||||
|
When the chroot session ends, the bind mounts are automatically cleaned up.
|
||||||
|
With the --daemon flag, the session is launched under strace so that every system call
|
||||||
|
from the chroot process and its children is logged. The logs are stored in a directory:
|
||||||
|
\$DAEMON_LOG_DIR
|
||||||
|
Each log file is post-processed to try to include the traced program's name (if found)
|
||||||
|
and trivial commands are ignored. Finally, the log directory and its files will have their
|
||||||
|
ownership and permissions changed so the invoking user (from \$SUDO_USER) can read and write them.
|
||||||
|
|
||||||
|
disconnect
|
||||||
|
Unmount the filesystems from the chroot.
|
||||||
|
Checks if bind mounts exist for \$CHROOT_DIR and, if so, unmounts them.
|
||||||
|
|
||||||
|
status
|
||||||
|
Displays the current mount status for the chroot jail (\$CHROOT_DIR).
|
||||||
|
|
||||||
|
install
|
||||||
|
Installs chroot_manager to /usr/local/bin, and copies the man page and bash completion file
|
||||||
|
(if found in the current directory) to the appropriate locations.
|
||||||
|
|
||||||
|
uninstall
|
||||||
|
Uninstalls chroot_manager from /usr/local/bin and removes the installed man page and bash completion file.
|
||||||
|
|
||||||
|
help
|
||||||
|
Display this detailed help message.
|
||||||
|
|
||||||
|
Options:
|
||||||
|
--verbose
|
||||||
|
Enable verbose/debug mode (more detailed logging to console and log file).
|
||||||
|
|
||||||
|
--daemon
|
||||||
|
When used with the 'connect' command, run the chroot session under strace in daemon mode,
|
||||||
|
logging all system call activity in separate log files.
|
||||||
|
|
||||||
|
Notes:
|
||||||
|
- Commands that modify the chroot environment (create, connect, disconnect, install, uninstall)
|
||||||
|
must be run as root.
|
||||||
|
- By default, the chroot jail is located at: \$CHROOT_DIR.
